Suyika Japanese Tetsubin Cast Iron Teapot (with infuser)

A popular tetsubin for loose leaf. It has the enamel lining that makes it safe and easy to clean for brewing (not just boiling), a removable stainless infuser basket for loose leaf, and the heavy cast iron body keeps the pot hot for a long steep. Tea drinkers like that it looks the part and holds heat far better than glass or ceramic.

A cast iron tetsubin holds heat beautifully, so loose-leaf tea steeps evenly and stays hot through a long session. The catch is that a real tea tetsubin needs an enamel lining inside, because bare cast iron is for boiling water, not brewing. Tea drinkers look for an enamel-lined pot with a removable infuser basket.
